Babe or girlfriend

What exactly does it mean when your boyfriend tells his friends you're not his girlfriend but his babe? And keeps depending on you for everything when he has his own money. I pay for transport,I cook. I'm not saying it isn't right to pay or stuff. But what if we never met? Because I'm sure, before we met,he pays for all his stuff. And now,I'm not even sure what we are. He talks to me like I'm an idiot. Saying he's only calm because I'm a girl and if I try something again, he'd do something about it. Am I just someone that pays his bills when nobody even knows who I am. He posts other girls picture with love emoji,not even mine😭😭😭
